Introduction
Approximately 9 million people in China use insulin but little is known of their injection techniques (IT). Our aim was to understand IT in China via direct examination and a detailed survey.
Methods
Injection Technique Questionnaire (ITQ) results of 3853 patients from 20 representative centers in China were compared with the Rest of World (ROW).
Results
Insulin pens are used by 92% of Chinese insulin injectors, with > 3/4 using 4- or 5-mm pen needles. This is consistent with Chinese BMI values (and thus subcutaneous fat thickness) being lower than in ROW, raising the risk of IM (intramuscular) injections with longer needles. Total daily insulin dose is ~ 33 IU in China vs. 45 IU elsewhere. Lipohypertrophy (LH) rates are lower than in ROW, but still found in at least 25% of Chinese patients. Patients apparently do not realize they have LH or are unaware of the hazards of injecting into LH since many of them do so, and those who do use a mean of 11 IU more of insulin than non-LH patients. This incremental insulin use possibly costs the Chinese health care service around 2 billion RMB annually. Needle reuse is also frequent in China (78% vs. 48% ROW), and the high cost of pen needles is the main reason patients cite for reusing (25% use a single needle > 10×).
Conclusion
This study reveals many areas in which Chinese professionals and patients can optimize injection practices and thereby improve outcomes and reduce costs. The official guidelines of the Chinese Diabetes Society, based on the FITTER recommendations, offer a roadmap for reaching this goal.
